Specification of Letters Patent.

Patented Nov. 3, 1914:.

Application filed June 16, 1914. Serial No. 845,395.

To all whom it may concern Be it known that I, ERNEST W. SKOLD- nnne, acitizen oi the United States, and a resident of the city of New York,borough of Brooklyn, in the county of Kings and State of New York, haveinvented a new and Improved Buoy, of which the following is a full,clear, and exact description.

My invention relates to buoys and has reference more particularly tomooring buoys for locating the anchoring position of vessels.

The buoys in use at present for mooring purposes are generally made ascans or casks and are liable to be punctured or crushed by blowsreceived from moving vessels, floating ice, wreckage and the like. Ifmade of wood or cork they become saturated and lose their floatingqualities. A further objection to buoys of this class is their liabilityto chafe the sides of vessels or otherwise injure them when striking thevessels. The buoys used for mooring purposes are generally provided withan axial bolt forming the connecting link between the anchor and thehawser of the vessel. This bolt forms a rigid, non-elastic connectionwhich is very detrimental to the mooring chain, due to the jerkingproduced by the motion of the waves on the buoy.

To obviate the above objections I provide a buoy which is practically`unsinkable and unaffected by the rough usage to which it is subjected,and which is adapted to give within certain limits and relieve thestrain on the mooring chain due to jerking caused by wave motions.

With the above and other objects in view, the nature of which willmorefully appear as the description proceeds, the invention consists in thenovel construction, combination and arrangement of parts as herein fullydescribed, illustrated and claimed.

In the accompanying drawings, forming part of the application, similar'characters of reference indicate corresponding `parts in both views, andFigure l is an elevation of an embodiment of my invention; `and Fig. 2is a fragmentary cross section on line 2-2, Fig. 1.

Referring to the drawings, 3 represents a flexible, impervious envelopmade of rubber cloth or other water-proof material;

and the envelop is filled with light, unsinkable material such as corkor kapok l. The envelop is preferably of an elongated ovoid form but ifdesired it may be made spherical or of' any shape that necessity maydemand. The rubber cloth forming the envelop is protected exteriorly bya strong canvas envelop 5. The protector 5 is provided on the exteriorsurface with tubular members 6, secured to the canvas bag or envelop inany suitable way, which form longitudinal pockets on said protector.Through each of the pockets passes a flexible member, such as a chain orcable 7,`the ends of which are united at the poles of the buoy by a ringor shackle S. To one of the rings may be attached the anchor chain; tothe other, the hawser of the vessel. The stress applied to said rings isdistributed through the flexible members 7 which form the cradle for thebuoy. It is self-evident that the sudden jerking `on the rings 8 causedby the motion of the waves when the buoy is afloat would tend tocompress the body of the buoy, but since the same is formed of materialwhich will give within certain limits, this sudden stress caused by thejerking on the mooring chain is reatly reduced. It may be said that thebody carrying the flexible members 7 is elastic within certain limitsand will give when stress is applied to the rings 8.

From the foregoing description, taken in connection with theaccompanying drawings, the advantage of the construction and operationof the device shown will be readily understood by those skilled in theart to which the invention pertains; and while I have described theprinciple of operation, together' with the device which I now con- Siderto be the best embodiment thereof, I desire to have it understood thatthe device shown is merely illustrative and that such changes may bemade when desired as are within the scope of the appended claim.

Havingthus described my invention, Il

claim as new and desire to secure by Letters Patent:

In a buoy,-a flexible, impervious envelop made of rubber cloth; afloating substance filling the envelop; a canvas bag fitting snugly overthe rubber envelop, said bag and envelop being of elongated ovoid shape;

tubular members on the exterior surface In testimony whereof have signedmy of the canvas bag formmg longltudmal name to thls speelfeatlon 1n thepresence of pockets thereon; fleXlble members engaglng two subserlblngWltnesses.
